Abstract

Filtre à air comprenant un boîtier (1) pour la pièce d'insertion, équipé d'un élément filtrant (3) constitué d'un filtre principal (31) et d'un pré-filtre (32) sur la surface qui est exposée à l'air entrant à travers la cuvette (11) délimitant le volume d'entrée (13) et qui s'écoule ultérieurement dans le couvercle (12) à travers la chambre de sortie (14), à l'état filtré, l'élément filtrant (3) présentant un joint circonférentiel (33) sur sa surface tournée vers le couvercle (12), l'étanchéité entre l'entrée et la sortie étant assurée par l'intermédiaire de l'élément filtrant (3). L'élément filtrant (3) est formé d'un filtre principal (31) dont la surface inférieure (311) est recouverte, pour l'entrée de l'air, d'un pré-filtre (32) qui est en saillie au moins sur un côté (312) et qui, à l'état monté, est incliné vers le bas par rapport à l'horizontale (HH). L'emplacement de montage de la pièce d'insertion (2) et de son élément filtrant (3) dans le boîtier (1) est limité sur la partie avant, par une nervure (112) qui forme un bord d'appui (121) en vue de comprimer localement le bord avant inférieur du pré-filtre (32), lorsque la pièce d'insertion est insérée, en vue de séparer et de dévier l'eau s'écoulant vers le bas, sur la surface extérieure du pré-filtre (32).
